As an astronaut, an engineer and a woman, Julie Payette will make her mark as governor general

JuliePayetteis one of 10 Canadians to go to space, and the second Canadian woman to do so.She has degrees in engineering, worked for IBM before joining the Canadian Space Agency, was chief operating officer of the Montreal Science Centre, speaks a half dozen languages, plays the pianoand is an accomplished singer.

On Thursday, Prime Minister Justin Trudeau will introduce her as Canada's next governor general.

The symbolism of that appointment officially made by the Queen, whomTrudeau spoke with last week will not be what some imagined it might be. But the country will soonbe officially represented by an accomplished female astronaut and scientist. And that has a symbolic quality all its own.

• Former astronaut JuliePayetteto be Canada's next governor general
• Justin Trudeau's neighbour says goodbye

There had been speculation that Trudeau would choose an Indigenous governor general, a potentially significant gesture toward reconciliation.

To some degree,Trudeaumight have fuelled such speculation when he hinted a year ago that he would have Canada's diversity in mind when he recommended a name to the Queen.

"I suspect I might be saying 'because it's 2017' when the time for that decision comes around to be explained,"he said in February 2016, a throwback tohis quip the previous fallwhen he appointed a gender-balanced cabinet.

"I can reassure you, I will take into account the nature of Canada and the desire of Canadians to see institutions and appointments across the government that reflect the diversity of Canada."

There is still, it might be noted, a seat on the Supreme Court to fill.

But now that she is here, Payette sounds like exactly the sort of governor general one might have expected Trudeau to seek out: having made a name for himselfas a feministand as someone who couldexplain quantum computing,Trudeauhas found a female astronaut to be the next governor general.

Payettewill be just the fourth woman to be governor general. And her appointment will keep with the tradition of alternating between a francophoneandan anglophone.

But she is also an incredibly accomplishedwoman involved in science, a pursuit that is still predominantly populated by men. She is already a role model.

Science also happens to be a fieldTrudeauhas tried to embrace, both as a mark of his government's own wisdom and as a vision for the future of the country's economy.

Recent events involving the lieutenant-governor following the electionin British Columbia have reminded us the governor general is an important backstop in how we govern ourselves, but it is mostly a symbolic post: quite literally, the Queen's representative and Canada's figurehead.

And though that could be dismissed as a remnant of our monarchical heritage, the office can help define the country and symbols can matter.

A short history of GGs

Governors general are freighted with symbolism, noted for the small changes they make, the causes they championor what they represent.

In practice, the office has evolved as Canada has, marked in certain ways by a series of firsts.

For the first 85 years of this country's existence, thegovernors generalwereBrits, all with aristocratic titles: six earls, four lords, three viscounts, twomarquessesand two dukes.

The first Canadian to hold the post was Vincent Massey in 1952.

Jeanne Sauvbecame the first woman to occupy the office in 1984. Ray Hnatyshyn, appointed in 1990, was a first-generation Ukrainian-Canadian. His successor, Romeo LeBlanc, was the first Acadian governor general.

Adrienne Clarkson, born in Hong Kong,was the first non-white governor general, the first immigrant to hold the title and the first person to come to the office from somewhere other than politics or the military.

Michalle Jean, a black woman, had fled to Canada with her family from Haiti.

On the day of Barack Obama's inauguration in 2008, a DJ set up in the ballroom of Rideau Hall spun a record by Gil Scott-Heron, the American spoken-word poet and civil-rights activist, as part of a gathering of young people to mark the new president's arrival.

It was perhaps not the sort of thing you would normally associate with the monarchy or the official residence of the Queen's representative. But it was quintessential of Jean'sloose and heartfelt term that seemed at times to push the office to be viewed differently.

By all such measures, the appointment of David Johnston in 2010 was neither historic nor flashy, even if it was still admirable.

The elevation of the former academic and university administratorseemed in keeping with Stephen Harper's aversion to fuss. Johnston was Canada'sbookish, kindly grandfather. He focused on ideas likephilanthropy, volunteerism, learning, family and children. Hewrote a book about the country. He inaugurated a new prize for innovation.

Johnston has had hisinteresting moments hetweaked the legal profession, addressed violence in hockey, commented on thecontroversy around the niqaband wascompelled to apologizefor comments about Indigenous Canadians but for the most part his term was marked by understatement.

Of course, there is much to be said for understatement.

Payette's turn to make a mark

Indeed, being an impartial symbol of an entire country necessarily requires a certain amount of understatement.

But amid the officialdom, there is still room to manoeuvre, or even merely to stand at home and abroad as a symbol of something.

It willperhaps be considered a missed opportunitythat the next governor general won't beIndigenous.

ButPayettewill symbolize other things. And soon, styled as Her Excellency, she will get to formally leave her mark.
